trigonometry

[south hound]

if ure good at pythagoras cmere

wtf i did a question and got it right, but it already had the units

why is adding something a cm squared unit? i was finding the area of a parallelogram + trapezium combined

[pallid swallow]

Can you elaborate on what you mean? I'm not sure if I understand.

[south hound]

nvm i figured it out

but im stuck#

@pallid swallow

[pallid swallow]

Well, we have:
S(shaded) = S(trapezoid) - S(triangle)
Which shape are you having trouble with?

[south hound]

i thought it was a trapezium so i did 15+25/2 and got 280 which is wqrong

[pallid swallow]

If a trapezoid has height h and bases a and b, then:
S(trapezoid) = h(a + b)/2
So, you forgot the height.

[south hound]

OH is the height 14

[pallid swallow]

Yes.

14 cm, to be exact.

[south hound]

okay thanks

let me do it again

WHAT its still wrong

it gave me a diff question

am i doing something wrong

has the triangle got something to do with it

[vague zealot]

All you need to do is the area of the trapeziod - the inside triangle

for the inside triangle you have the base and height

So the area is 1/2 * 6 * 11

which is 33

the total trapezoid's area is h/2 (a + b) where a and be are the bases which are parallel to eachother

[south hound]

OH

okay THANK YOU

[vague zealot]

so the area is 7 (25 + 15)

[south hound]

i didnt understand that at all

[vague zealot]

Yep

[vague zealot]

Wait what lol

Do you get it now?

[south hound]

NO LIKE BEFORE

yeah

LOL

thank you

[vague zealot]

OH OKAY LOL

Yw

[south hound]

let me do my workings out

[vague zealot]

Okay, lmk if you have any more questions I'll be happy to help

[south hound]

OMG OKAY TYHANKS

yay i did it right

im trting to improve in maths

uh

[vague zealot]

Well do you know what sin(x) means?

here I'll give you three options you choose the right one

1. opposite side/hypotenuse

2/ adjacent side/hypotenuse

3. opposite side/ adjacent side

The first one is correct

So basically in this, sin(68) = y/5.1

[south hound]

isnt sin = soh so we're using opposite and hyp???

[vague zealot]

to calculate y just multiply both sides by 5.1

[south hound]

IDK

[vague zealot]

Yes

[south hound]

eww i dsont like this

LOL

okay let me try

[pallid swallow]

Well, I wrote it 😄

[south hound]

I UNDERSTAND NIW

sin(68)= 5.1/y???? @vague zealot

[vague zealot]

and then use your calculator

[vague zealot]

No lol

[south hound]

2WHAT 😭

[vague zealot]

Sin(68) is y/5.8 bc 5.8 is the hypotenuse

[south hound]

OH

[vague zealot]

Hypotenuse is the side thats slanted

I guess thats a bad way of remembering it if the triangle is tilted or something

[south hound]

LMFAO

i thoughjt it was

[vague zealot]

But its the side that isnt perpendicular to any other side

[south hound]

right angle = hyp

angle = opp

other side adjacent

[pallid swallow]

5.1. But yeah.

[vague zealot]

Oh yeah lmao sorry

[vague zealot]

The side opposite to the right angle is the hypotenuse

[vague zealot]

Idfk what this means so uh

[south hound]

i got it wrong

what

UJ4RGUGHGHGH

[pallid swallow]

What did you get?

[south hound]

whats the answer someone j tell me 😭

-4.5???

[pallid swallow]

Uh, no...

How can a side be negative?

How did you calculate it?

[vague zealot]

Okay what did you say sin(68) was? It should be sin(68) = y/5.1

then you multiply each side by 5.1

[pallid swallow]

Oh, I know why.

Your mistake, both of you, is that you write sin(68).

There is not sin(68) here.

[south hound]

IM SO CONFUSED

WHAT IS GOING ON

[pallid swallow]

There is, however, sin(68°).

[south hound]

LMFAO

mathsa

is gonna cause me to have a fat panic attack

[vague zealot]

OKAY WELL I THOUGHT SHE DOESNT KNOW RADIANS SO SHE'D JUST USE DEGREES

But yes its in degrees he's right

[south hound]

HELP 😭

WHATS GOING ON

[vague zealot]

Okay is your calculator on radian mode

Because if it is switch it to degrees

[pallid swallow]

Well, if you use a calculator, the default setting is radians.
Also, why the caps?

[south hound]

im using my google calculator

[pallid swallow]

No need for that.

[vague zealot]

Yeah pretty sure that also has a default for radians

[vague zealot]

Is this what modding is lmao

But sure

If you insist

[pallid swallow]

Modding? What do you mean?

[south hound]

i sorted it

i got

4.7

[pallid swallow]

Anyway, the answer should be 5.1sin(68°).

[south hound]

donedone

[pallid swallow]

Yes.

[south hound]

im so confused on this one if someone could help

[vague zealot]

Didnt you get the answer?

[south hound]

yes this is another one

[vague zealot]

Bruh are you just getting us to do your homework for you

[south hound]

nuh uh

[vague zealot]

See the radians

You gotta switch it to degrees

its on the left side

[south hound]

OKAY let me do that

OH

I SEE

OKAY

[vague zealot]

Lol

[south hound]

okay ill do it again

[pallid swallow]

I recommend switching to a more capable calculator. Like a pocket engineering one. Or Wolframalpha, etc.

[south hound]

its not liking me right now

[south hound]

is that on google#

[pallid swallow]

Is what on Google?

[south hound]

those calculators

[pallid swallow]

Well, uh...

Pocket calculator isn't an app.

It's a calculator that you carry around.

[south hound]

OH

[pallid swallow]

Wolframalpha is https://www.wolframalpha.com/.

[south hound]

ive got like 3 different answers im so confused

[pallid swallow]

What did you get?

[south hound]

i got

0.9 for one

and i used a diff calc

i got

0.0003

[vague zealot]

Was it set to radians?

[pallid swallow]

No, that isn't possible.

[south hound]

IT WAS SET TO DEGREES

idk whats going on

uhyh

uhh*

i defo have the calc right

[pallid swallow]

Well, what is the expression you're typing in?

[south hound]

cos(55)x5.9

😭

[pallid swallow]

Type 5.9cos(55 deg) into Wolframalpha.

[south hound]

im so bad at this maths thing

OKAY

im sorry darp 😭

[pallid swallow]

Don't worry!

This isn't a math problem, just a problem with notation.

When you write expressions with degrees, always specify where you mean degrees: write "degrees", "deg" or just the usual symbol °. That way you won't forget.

[south hound]

URGHH yeah i hate calculators sometimes

okay done!!

got itright :D

thank you im sorry again

ugh they give me calculations WITHOUT DIAGRAMS

DRIVES ME INSANEEE

wouldnt this be 3.4cos(13)

[pallid swallow]

Well, again. Specify the degrees.

[south hound]

OKAY

[pallid swallow]

If you're using Wolframalpha, type 3.4cos(13 deg).

[vague zealot]

What does dp mean?

Dynamminc programming?

Jk

[south hound]

decimal place

LOL

[vague zealot]

Im guessing decimal points

I see

[south hound]

YEAHH thanks

[pallid swallow]

Yes.

Also, Fufu, what did you mean by "modding"? Are you talking about a video game?

[slate bramble]

@quiet drum has given 1 rep to @pallid swallow

[south hound]

OMG I DID IT RIGHT

[pallid swallow]

Great!

[south hound]

SLAY

SAY SLAY DARP

[pallid swallow]

Oh, hold on. Did you mean "moderating"?

If so, I'm not a moderator.

[south hound]

@pallid swallow

[pallid swallow]

Yes?

[vague zealot]

Seemed like you were mini-modding

[south hound]

say slay!!

[vague zealot]

As useful as that can be sometimes, its not too useful in certain circumstances

[pallid swallow]

Wait, so you actually meant modding? Then I don't understand.

[pallid swallow]

Slay? Slay what?

[south hound]

just slay!

[vague zealot]

Yes I did.

[south hound]

apparently this is wrong

[pallid swallow]

Hm. Can you elaborate, then? I am not a modder.

[pallid swallow]

Well, express h first.

[south hound]

wdym byt that

[vague zealot]

Rather than entering the equation you could just enter tan(7) * 3.2

[south hound]

OH

[vague zealot]

Well you see theres an equation right

[pallid swallow]

More specifically, 3.2tan(7 deg).

[vague zealot]

So to solve the equation you express it in terms of the other stuff

[south hound]

done it guyss

lemme try

this one on my own]#

[vague zealot]

And yeah I think it did it in radians?

because it sais 7pi/180

[south hound]

DARP SLAY I DID IT @pallid swallow

yess i did one on my own omg go me

[pallid swallow]

Good job!

[south hound]

omt

this ones making me cry

[pallid swallow]

I still don't know what you mean by "slay" and Fufu means by "modding", though...

[south hound]

SLAY MEANS LIKE

go me!!

[pallid swallow]

Oh.

Then, slay, I suppose.

[south hound]

LOL

is it this

[vague zealot]

yep

[pallid swallow]

Yes.

[south hound]

YAY

[vague zealot]

Don't mess it up when you plug it into the calculator though

[south hound]

i didnt

slay

its so hard to write on pc

[pallid swallow]

Yes.

[south hound]

i need rewards for thisd

LOL

should i do my target work

its not compulsory but im bad i do needa revise 😭

[pallid swallow]

What is target work?

[vague zealot]

Whats target work?

[south hound]

its like

stuff u got wrong

put into a separate area

and you focus on that and keep doing it

[pallid swallow]

Oh. Well, if you have time, better to do it now, so you don't lose focus.

[south hound]

OKAY

can i keep this oepn

[vague zealot]

Sure?

[pallid swallow]

Sure!

[south hound]

ill do these and then finish up

i might need help w these thats all

saving this for another day 😭

LOL DARP @pallid swallow

[pallid swallow]

Heh. I remember that. Was pretty silly...

[south hound]

im looking for the fully factorised one

[pallid swallow]

Well, the first one, of course.

Or (x - h)^2, doesn't matter.

[south hound]

ITS SAYING ITS ALL WRONMG

[pallid swallow]

Well, there's an (x - h)^2 that should be correct.

[south hound]

urghhhhhhhhhh this question is driving me insane

okay let me try

YES

IT WORKED

[pallid swallow]

Don't worry if it marks it as wrong. We've already established before that this question was faulty.

Oh, it did? Great!

[south hound]

such a dumb questiopn LOL

yeah i finsihed the other bits on my own

im gonna do those other sections now

[south hound]

ffs im gonna cry

[pallid swallow]

What's wrong?

[south hound]

its not letting me do it in degrees

[pallid swallow]

To convert from radians to degrees, multiply the result by 180°/π.

[south hound]

WHAT

im so confused

my brains just

mashed

[pallid swallow]

π radians is equal to 180°. So, to convert from radians to degrees, you multiply by 180°/π, and to convert from degrees to radians you multiply by π/180°.

[south hound]

180 divided by pi????

WHAT

someone kill me

[pallid swallow]

Why are you finding this weird?

[vague zealot]

I think you're making this harder for yourself than it needs to be

radians is another type of unit to measure angles, just like degrees

[south hound]

short answer: i hate maths

[pallid swallow]

Yeah, just more natural than degrees.

[vague zealot]

The conversion between degrees and radians is pi/180, as lord darpinger said

[vague zealot]

As I said if you hate something getting better at it just becomes harder

[south hound]

idk how maths is enjoyable

[pallid swallow]

Well, I like it because I get to discover some interesting patterns and dependencies, as well as solve interesting problems.

[vague zealot]

For me problem solving is enjoyable

[pallid swallow]

And Fufu is right: hating anything will make it harder.

[vague zealot]

Math is a way to do that so I find it enjoyable

[vague zealot]

Yeah

[pallid swallow]

Relax for a bit, take a break if you're tired.

[south hound]

about

to rip

my hair out

[pallid swallow]

Come on, you need a break.

You can continue this later.

[south hound]

I NEED TOFINISH IOT

I NEED TO

going to cry

wait already crying

slay

[pallid swallow]

Calm down.

[south hound]

maths

makesme cry

[vague zealot]

Jesus christ

[south hound]

LMFFAOO

[vague zealot]

Something I've found is that if you make something part of your identity it gets harder to change and improve at it

Like if you say you sucking at math is part of your identity

[pallid swallow]

As I said, if you want to convert from radians to degrees, you need to multiply by 180°/π.
Thus, type (180°/π)arcsin(53/82).

[vague zealot]

Then you'll go around telling random people that and making them think of you as that rather than trying to actually improve. So set aside your hatred for math for a few hours and just methodically try solving

[vague zealot]

Yeah

You could just write deg as well

[pallid swallow]

Yes.

[south hound]

omggggg i cant stand this

HJOW MANY ANSWERS AMN IU GINNA GWET

THE FUCL

THE FDUCK*

[pallid swallow]

What do you mean?

[south hound]

kill me plz

omg

35+18 = 53

sin-1=(53/82)

[vague zealot]

do you know the inverse trig functions?

[south hound]

WHAT IS IT NOT WORKING FOR SMH

[pallid swallow]

Well, this seems to be the same one as before.

[vague zealot]

Yeah bc youre using tan

[south hound]

for fuck sake

i hate

this

[vague zealot]

53/82 is opp/adj

[south hound]

kill me

[pallid swallow]

Oh, actually, yeah! We all just got confused.

[south hound]

im done

I AM DONEEEE

[pallid swallow]

Come on, calm down. Let's just finish the tasks and you can go rest.

[vague zealot]

Stop wasting your time texting here and go actually attempt each problem with a focused mindset

[south hound]

im gonna

do this

again

one sec

[vague zealot]

Then come here and ask for help if you need it

[south hound]

tears of fucking joy

gonna do this enxt dumb question

[pallid swallow]

Better not to go further with that mindset. As I said, better to calm down, then continue.

[south hound]

shall i do this or save my sanity

[pallid swallow]

Well, is it the last one?

[south hound]

for my targets

then i have an xp boost but i cba w that

thats all the questions in it

[pallid swallow]

XP boost? Huh...
This whole thing sounds like a video game. Quite strange.

[south hound]

its such a bad maths programme

LOL

i might just

do it another day

[pallid swallow]

Yeah, that would probably be better.

[south hound]

in my defense ive done like

30 questions

im gonna

nrver

TOUCH MATHS
